I am a new guy to this forum with a B2601 that has a loader and backhoe that I bought new last year. I really like the machine overall but the seat is a sad piece of engineering on an otherwise very well done little machine. Tell me please, how do you keep this seat from constantly popping up? I screw the tensioner in and out tight and not; hand push the holder and tighten.....over and over but without fail pretty much every 3rd time I get off the tractor the seat pops up. What's up with this? I surely can't be the only one experiencing this. Thanks for any advice in advance.
